Special K, here is the scoop on deutz-allis. I guess I did not have it quite right, Deutz bought Allis before AGCO, I copied this off the web:

"In 1984, Allis-Chalmers was in a difficult position and the company was purchased by Deutz. Deutz rebranded the Allis tractors as Deutz-Allis and began importing Deutz-Fahr tractors under the Deutz-Allis name. The switch to green, from the traditional Allis orange, was a disappointment for loyal Allis-Chalmers farmers.In 1991, the Deutz-Allis company was sold to AGCO, which renamed the brand as AGCO Allis and returned to the orange paint scheme. The AGCO Allis name was dropped by AGCO in 2001."
